Description
Die Erfindung betrifft einen vollständig recyclingfähigen Tuf tingteppich, dessen wesentliche Bestandteile aus Polymeren derselben Polymerfamilie bestehen sowie dessen Herstellung und Verwendung.The invention relates to a fully recyclable tuf carpet, the essential components of which are made of polymers consist of the same family of polymers and its production and Use.
Sie betrifft insbesondere Teppiche, deren dimensionsstabiles Trägervlies als Erstrücken, die Polgarn-Noppen, die textile Rückenausstattung als Zweitrücken und die jeweils benötigten Kleber aus Polymeren derselben Polymerfamilie bestehen.It particularly affects carpets, their dimensionally stable Backing fleece as backing, the pile yarn knobs, the textile Back equipment as a second back and the respectively required Adhesives consist of polymers from the same family of polymers.
Tuftingteppiche bestehen aus einem Grund- oder Trägermaterial, auch Erstrücken genannt, das ein Bändchengewebe und/oder ein Vlies sein kann, mit eingearbeiteten Noppen eines Polgarnes aus Synthese- oder Naturfasern. Das Polgarn ist mit Hilfe eines Vorstrichs im Trägermaterial fest verankert. Das entstehende Zwischenprodukt wird als Halbfertigware bezeichnet. Bevorzugte Vorstriche sind solche auf Basis von Naturlatex oder von Synthese- Latex.Tufted carpets consist of a base or base material, also called first back, which is a ribbon fabric and / or a Can be fleece, with incorporated knobs of a pile yarn from synthetic or natural fibers. The pile yarn is with help of a primer firmly anchored in the substrate. The The resulting intermediate product is a semi-finished product designated. Preferred primers are those based on Natural latex or synthetic latex.
Ein weiterer wesentlicher Teppichbestandteil, der Zweitrücken, kann ebenfalls eine, bevorzugt als Schaum aus Latex mit Antei len an Stabilisatoren, Seifen und Füllstoffen aufgebrachte La texschicht oder ein textiles Flächengebilde oder Polyurethan schaum sein.Another essential component of the carpet, the backing, can also be one, preferably as a latex foam with antei len applied to stabilizers, soaps and fillers tex layer or a textile fabric or polyurethane be foam.
Damit weisen die zur Teppichherstellung verwendeten wesent lichen Bestandteile eine völlig unterschiedliche Zusammenset zung auf, die die Rückführung und Wiederverwertung der Teppiche nicht gestatten, da die Auftrennung zu aufwendig ist. Speziell die einwandfreie Trennung der Garnnoppen vom Latex ist nahezu unmöglich. Thus, the essentials used for carpet manufacture completely different composition on the recycling and recycling of Do not allow carpets because the separation is too complex. Especially the perfect separation of the yarn nubs from the latex is almost impossible.
Darüberhinaus stellt Latex eine Umweltbelastung dar, die zum vernetzenden Ausreagieren und Verankern der Polnoppen oder Verfestigen des Zweitrückens benötigten Temperaturen setzen organische Substanzen frei.In addition, latex is an environmental burden, which cross-linking outreach and anchoring of the pimples or Solidify the secondary back to set the required temperatures organic substances free.
Für die vorliegende Erfindung bestand die Aufgabe, einen Tep pich zu schaffen, dessen Zusammensetzung aus synthetischen Polymermaterialien ein direktes und voll ständiges Recycling erlaubt, und in dessen Herstellungsverfahren die Emittierung von Schadstoffen wesentlich herabgesetzt ist.For the present invention, the task was a tep pich to create its composition from synthetic Polymer materials direct and complete recycling allowed, and in its manufacturing process the issue of pollutants is significantly reduced.
Die Lösung dieser Aufgabe ergibt sich aus den recyclingfähigen Tuftingteppichen gemäß Anspruch 1, dem Verfahren gemäß Anspruch 14 und der Verwendung der recyclingfähigen Teppiche nach den Ansprüchen 21 und 22.The solution to this problem arises from the recyclable Tufted carpets according to claim 1, according to the method Claim 14 and the use of recyclable carpets according to claims 21 and 22.
Die Bestandteile der erfindungsgemäßen Tuftingteppiche, das Träger- und Grundmaterial, auch Erstrücken genannt, das Polnoppen-Garn, die textile Rückenausstattung, auch Zweitrücken genannt, und die notwendigen Kleber gehören alle derselben Polymerfamilie, bevorzugt den Polyamiden oder den Polyestern an.The components of the tufted carpets according to the invention, the Base and base material, also called first backing, the Polnoppen yarn, the textile backing, too Called second back, and all the necessary glue belongs the same family of polymers, preferably the polyamides or Polyesters.
Damit wird die Tatsache genutzt, daß die Polymertypen einer Polymerfamilie durch Variation der Kettenbausteine und Ketten länge in ihren physikalischen Eigenschaften, wie zum Beispiel den Festigkeiten oder den Schmelz- und Klebetemperaturberei chen, verändert werden können. Mischungen davon können in wei ten Bereichen zur Herstellung von Regeneratfasern eingesetzt werden. Damit sind die Teppiche ohne die Notwendigkeit einer Materialtrennung vollständig recyclingfähig. This takes advantage of the fact that the polymer types are one Polymer family by varying the chain building blocks and chains length in their physical properties, such as strength or melting and adhesive temperature range chen, can be changed. Mixtures of these can be in white areas used for the production of regenerated fibers become. So the carpets are without the need for one Material separation completely recyclable.
Vorteilhaft für die erfindungsgemäßen Teppiche sind Trocken- oder Spinnvliese als Trägermaterial, besonders von solchen die mit Klebern und/oder Klebefasern derselben Polymerfamilie ver festigt bzw. thermobondiert sind. Besonders vorteilhaft ist sowohl der Austausch des herkömmlichen Zweitrückens aus Latex durch eine einheitliche aus Fasern derselben Polymerfamilie bestehende textile Rückenausstattung, bevorzugt aus der Gruppe der Gewebe, Vliese und Filze, als auch der Ersatz der für die Fixierung verwendeten Latex-Kleber durch Schmelzkleber dersel ben Polymerfamilie, aus der die übrigen Teppichbestandteile stammen. Die Schadstoffemission lädt sich dadurch wesentlich verringern.Dry carpets are advantageous for the carpets according to the invention. or spunbonded nonwovens as a carrier material, especially those ver with adhesives and / or fibers of the same polymer family are strengthened or thermobonded. It is particularly advantageous both the replacement of the conventional secondary back made of latex through a uniform one made of fibers from the same polymer family existing textile backing, preferably from the group the fabrics, fleeces and felts, as well as the replacement of those for the Fixation used latex glue through hot melt glue dersel ben family of polymers from which the remaining carpet components come. The pollutant emission thereby loads up significantly reduce.
Somit sind in den erfindungsgemäßen Teppichen die Polgarn-Nop pen im Träger- oder Erstrücken mit Klebern derselben Polymerfamilie verankert, wobei die Kleber pastenförmige oder Hotmelt-Schmelzkleber sein können, die einen Schmelzbereich zwischen 100 und 150°C, bevorzugt zwischen 100 und 130°C aufweisen. Bevorzugte Schmelzkleber sind Copolyamide und Copolyester.Thus, the pile yarn nops are in the carpets according to the invention pen in the carrier or first back with adhesives of the same Anchored polymer family, the adhesive pasty or Hot melt hot melt adhesive can be a melting range between 100 and 150 ° C, preferably between 100 and 130 ° C exhibit. Preferred hot melt adhesives are copolyamides and Copolyester.
Die für die Fixierung der textilen Rückenausstattung, des so genannten Zweitrückens in den erfindungsgemäßen Tuftingtep pichen eingesetzten Kleber sind pulver-, pastenförmige oder Hotmelt-Schmelzkleber derselben Polymerfamilie wie die übrigen Teppichbestandteile, wobei Copolyester oder Copolyamide besonders bevorzugt sind.The one for fixing the textile backing, so mentioned back in the tufting tep according to the invention The adhesives used are powder, paste or Hot melt hot melt adhesive from the same family of polymers as the rest Carpet components, being copolyesters or copolyamides are particularly preferred.
Ein weiterer wesentlicher Vorteil der erfindungsgemäßen Tep piche liegt in der Möglichkeit, den Zweitrücken ganz oder zu mindestens teilweise aus Fasern herzustellen, die als soge nannte Regeneratfasern aus dem Recyclingprozeß der erfindungsgemäßen Teppiche stammen. Solche Regeneratfasern können aus den rückgeführten Teppichen, die nur gesäubert und zerkleinert sein müssen, durch Wiederaufschmelzen und Verspinnen der Schmelze in bekannter Weise hergestellt sein, wobei sich ein Trennen der Teppichbestandteile erübrigt.Another significant advantage of the Tep according to the invention piche lies in the possibility of completely or closing the back at least partially to be made from fibers that are known as so-called called regenerated fibers from the recycling process of carpets according to the invention originate. Such regenerated fibers can from the returned carpets that are just cleaned and must be crushed, by remelting and Spinning the melt can be produced in a known manner, a separation of the carpet components is unnecessary.
Die Herstellung des erfindungsgemäßen Tuftingteppichs besteht im wesentlichen aus den Schritten des Tuftens der Polgarn-Nop pen in den Erstrücken, der nachfolgenden Verankerung der Noppen mit den pastenförmigen oder Hotmelt-Schmelzklebern der gleichen Polymerfamilie wie die übrigen Teppichbestandteile und der anschließenden Fixierung des Zweitrückens auf dem vorgefertigten Halbfabrikat, der bevorzugt ein textiles Flächengebilde aus der Gruppe der Gewebe, Vliese, Raschelware und Filze aus Fasern derselben Polymerfamile ist, an den Erstrücken bzw. der Halbfertigware mittels Schmelzklebern die ebenfalls derselben Polymerfamilie angehören.The tufting carpet according to the invention is produced essentially from the steps of tufting the pile yarn nop pen in the back, the subsequent anchoring of the Knobs with the pasty or hot melt hot melt adhesives from same polymer family as the other carpet components and the subsequent fixation of the second back on the prefabricated semi-finished product, which prefers a textile Flat structures from the group of fabrics, nonwovens, Raschelware and felts made from fibers of the same polymer family to which First, or the semi-finished product using hot melt adhesive also belong to the same family of polymers.
Diese Verankerung und/oder Fixierung wird ausgelöst durch Erwärmen der zusammengefügten Bestandteile auf den Schmelz bereich der verwendeten Schmelzkleber, bevorzugt auf Tempera turen zwischen 100 und 150°C, besonders bevorzugt zwischen 100 und 130°C, und nötigenfalls unter Druck. Dabei kann der Schmelzkleber in Pastenform oder als Pulver oder aber als Schmelze mittels Breitbanddüse oder Transferwalze oder Rakel aufgetragen werden. Beim Auftragen des Klebers für die Fixie rung in Pastenform besteht diese in bekannter Weise aus Wasser, Dispergiermittel und Gleitmittel.This anchoring and / or fixation is triggered by Heating the assembled components to the enamel range of hot melt adhesives used, preferably tempera doors between 100 and 150 ° C, particularly preferably between 100 and 130 ° C, and if necessary under pressure. The Hot melt adhesive in paste form or as powder or as Melt using a broadband nozzle or transfer roller or squeegee be applied. When applying the glue for the fixie tion in paste form consists of this in a known manner Water, dispersant and lubricant.
Das erfindungsgemäße Verfahren und die damit hergestellten Teppiche sind in vorteilhafter Weise umweltfreundlich. Es werden keine zusätzlichen Chemikalien und keine fremden Poly meren verwendet und die Verklebungsreaktionen finden nur unter kurzzeitiger Temperaturerhöhung statt.The method according to the invention and the so produced Carpets are advantageously environmentally friendly. It no additional chemicals and no foreign poly meren used and the sticking reactions can only be found under brief temperature increase instead.
Die erfindungsgemäßen Tuftingteppiche lassen sich auch zum Herstellen von geformten, speziell von warmverformten Teppich teilen verwenden. The tufted carpets according to the invention can also be used for Manufacture of molded, especially thermoformed carpets use share.
Ein wesentliches Ziel ist die Verwendung der gebrauchten und zu entsorgenden erfindungsgemäßen Tuftingteppiche im Recyclingprozeß zur Herstellung von Regeneratfasern, die zumindest teilweise in Erstrücken und/oder Zweitrücken der recyclingfähigen Teppiche wiederverwendet werden können.An essential goal is the use of the used and to be disposed of tufted carpets according to the invention in Recycling process for the production of regenerated fibers at least partially in first back and / or second back recyclable carpets can be reused.
Beispielhaft werden Tuftingteppiche aus Erstrücken, Polgarn vom Halbkammgarn-Typ, Kleber und textilem Zweitrücken hergestellt, wobei die verwendeten Polymeren alle derselben Polymerfamilie angehören. Als Erstrücken wird ein thermobondiertes Trockenvlies oder Spinnvlies verwendet.Examples are tufted carpets made from ridges, Polgarn of the semi-worsted type, glue and textile backing made, the polymers used all the same Belong to the polymer family. As a first step is a thermobonded dry fleece or spunbond used.
Ein thermobondiertes Trockenvlies besteht aus einer polymereinheitlichen Mischung von 10-20%, einer Schmelzbindefaser oder 40-70% einer Klebefaser mit 80-90%, resp. 30-60% einer Trägerfaser.A thermobonded dry fleece consists of a polymer-uniform mixture of 10-20%, one Melt binding fiber or 40-70% of an adhesive fiber with 80-90%, resp. 30-60% of a carrier fiber.
Der aus Regeneratfasern hergestellte -textile Zweitrücken ist so konstruiert, daß er den bisherigen Latexschaum oder den Textilrücken ersetzt. Dies geschieht durch Einsatz grobtitriger Regeneratfasern, insbesondere im Bereich von 6,7-44 dtex. Je nach Komfortanspruch liegt das Gewicht zwischen 100 und 500 g/m2.The textile back made of regenerated fibers is designed so that it replaces the previous latex foam or textile back.
